ARMAND H. PEYCKE, OF CHICAGO, ILLINOIS, ASSIGNOR 'I'O AMERICAN STEEL FOUNDRIES, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY.

EQUALIZER MECHANISM.

Specification of Letters Patent.

Patented Dec. 2, 1919.

Application filed May15, 1918. Serial No. 234,574.

To all whom it may concern:

Be it known that I, ARMAND H. PEYCKE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and. useful Improvements in Equalizer Mechanism, of which the following is a specification.

This invention relates to equalizer mechanism.

One object of this invention is to prevent interference between brake mechanism and car under structure in rounding short curves:

Another object is to provide an equalizer mechanism adapted to meet requirements for extreme service conditions.

These and other objects are accomplished biymeans of the arrangement disclosed on t e accompanying sheets of drawings in which, 1

Figure 1 is a fragmentary. plan view of brake equalizer mechanism, arranged in accordance with my invention.

Fig. 2 is a fragmentary side elevation of the same. r

Fig. 3 is a detailsectional view, taken in the plane of line 3-3 of Fig. 1.

Flg. 4-. is a perspective view of the arrangement disclosed in Figs. 1 and 2, and

Fig. 5 is a perspective view of a modification of my invention.

The various novel features of my inven tion will be apparent from the following description and drawings and will be particularly ointed out in the appended claims.

Re erring to Figs. 1 to 4, incluslve, 1t W111 be noted that I have shown a truss type of brake beam having a tension member 10 and a compression member 11, there being brake heads 12 at the end of the beam carrying break shoes 13 for frictionally engaging the brakin surfaces of associated truck wheels let. H ngers 15 are connected to the brake head-for supporting the brake beam and associated parts. Interposed between the tension and compression members 10 and 11, is

a fulcrum 16 to which is pivotally connected 7 the lower end of a brake lever 17 to the upper end of which is connected a link 18 which in turn is pivotally connected to one end of a main equalizing bar 19. To the other end of the main equalizing bar 19 is pivotally connected a pull rod 20, there be mg an associated .pull rod 21, which 1s pivotally connected to an intermediate of the brake lever 17.

In some types of cars, it is found that where a body pull rod is connected to the main equalizing bar, the brake pull rods and other associated parts interfere with the unportion der structure of the car in rounding short curves, sometimes resulting seriously. More specifically stated, if the body pull rod is connected directly to the main equalizing bar, a force is developed tending to pull the rigging to one side or the other when rounding curves. To overcome this undesirable feature I have connected an auxiliafy equalizing bar 20 to the. main equalizing bar by links 21', which extend from the ends of the auxiliary equalizing bar to intermediate portions of the main equalizing bar. Pivotally connected to the auxiliary equalizing bar is a body pull rod 22. By means .of this arrangement short curves may be rounded without encountering interference difiiculties.

Secured to across bar or truck end sill 23 of the car truck is a supported loop member 24 for supporting the main equalizing bar 19 and its associated parts, the main equalizing bar sliding upon the lower portion of the loop member 24. A brake releasingspring 25 is also connected to this frame member 23- for ope'ratively engaging the compression member-'11 of the brake beam.

By referring to Fig. 5, it will be noted that I have shown my invention as applied to the bar type of beam 26, having brake levers 27 operatively connected thereto through fulcrums 28, intermediate portions of the brake levers being pivotally connected to, pull rods 29 and the upper end of said levers being connected by a main equalizing bar 30. This main equalizing bar is connected to an auxiliary equalizing bar 31 by links 32 and the auxiliary equalizing bar 31 has connected thereto intermediate its ends a body pull rod 33.

There may be other modifications of the invention and it is my intention to cover all such which do not involve a departure from the spirit and scope of the following said fulcrum a main equalizing bar, a link connection between said lever and one end of said main equalizing bar, a pull rod connected to the other end of said main equalizing bar, and an auxiliary equalizing bar operatively connected to said main equalizing bar.

2. In brake mechanism, the combination of a brake beam, a fulcrum member connected thereto, a brake Lever connected to said fulcrum, a main equalizing bar, a link connection between said lever and one end of said main equalizing bar, a pull rod connected to the other end of said main equalizing bar, an auxiliary equalizing bar, links connecting said main and auxiliary equalizing bars, and a body pull rod connected t said auxiliary equalizing bar.

Signed at Chicago, Illinois, this 9th day of May, 1918.

ARMAND PEYCKE.
